Flicker analysis and methods for electric arc furnace flicker (EAF) mitigation (a survey)

This paper gives a general review about how to examine/assess voltage flicker and methods followed in measuring flickers due to an arc furnace and means for its mitigation. It also investigates fast response static VAr generator (SVG) for arc furnace flicker mitigation. It includes discussion on the effects of utilities´ conditions, compensator response-time and compensator capacity on arc furnace flicker reduction. A comparison between SVC (static VAr compensator) and SVG on the applications of EAF compensation is carried out. Some discussions about the perspective of applying SVG for EAF compensation are also included in this paper
